My mount is having seizures :(

[HunterHarling]

First off, it's been a VERY long time since I had guiding issues, I usually get less than .5 rms guiding so it having issues now is very strange. Also, I'm using an EQ6 atlas mount with phd, SGP, loadstar, Edge hd, and OAG

So every now and then, the mount will absolutely "gun it" while guiding and send the guide star far out of the guiding box. I have no idea what is causing this, it will be going perfectly fine and then do this out of the blue... I've also confirmed it's not the dither or cable snags doing it.

 

So what do you think it could be??

 

Thanks in advance for any help.

Is this in RA or DEC?

Might be best to post a guidelog that includes a Calibration.
